川东南地区志留系油气成藏主控要素分析

Main Control factors of Silurian Hydrocarbon Reservoir in Southeastern area,Sichun Province

川东南地区志留系具有优质烃源岩及盖层封盖能力,并具有良好的生储盖空间配置,一直是南方海相下组合勘探的热点区域。根据野外勘察、钻井资料及测试资料分析,认为燕山期以来的盖层区域保存能力是该区志留系油气成藏的主控要素。

The southeastern area is the hot spot for the early Palaeozoic exploration because of its excellent hydrocarbon and good sealing ability. Also, the hydrocarbon, reservoir bed and sealing bed place well in space. We consider that conservation ability controls the Silurian hydrocarbon reservoir since the Yanshanian Movement period on the basis of field investigation, well data analysis and experimentation.
